--- Comment #3 from hutchinsonandy at gcc dot gnu dot org 2009-12-22 21:18 --- Created an attachment (id=19375) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=19375&action=view) PATCH to add avr-c.c Here is patch that I believe moves out the C related stuff to avr-c. builtin_define_std and cpp_define are undeclared - since they have no prototypes - which is pretty ugly. Compiler now builds without disabling LTO - BUT I now have LTO/WHPR problems with LD that is possibly a different bug. I would like opinion on this before concluding the problem is fixed or indeed solution is getting closer. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42457

--- Comment #2 from pinskia at gcc dot gnu dot org 2009-12-22 03:29 --- A way to fix this is to have avr-c.c like most other targets have. And declare avr_cpu_cpp_builtins in there. Note this change broke other languages besides C/C++/Objective-C/Objective-C++ so this is a regression as at one point Ada was building. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 GCC host triplet|i686-pc-linux-gnu | GCC target triplet|avr-unknown-none|avr-*-* Keywords||build Last reconfirmed|-00-00 00:00:00 |2009-12-22 03:29:41 date|| Summary|AVR fails to build unless |[4.5 Regression] AVR fails |LTO is disabled |to build with other than C ||family languages Target Milestone|--- |4.5.0 Version|lto |4.5.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42457
